Subject: [OASIS Issue Tracker] (ODATA-557) Allow exponential notation for Edm.Decimal
[ https://issues.oasis-open.org/browse/ODATA-557?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=60660#comment-60660 ] Michael Pizzo commented on ODATA-557: ------------------------------------- What does the service do if a client makes a $metadata request with a max odata version of 4.0? > Allow exponential notation for Edm.Decimal > ------------------------------------------ > > Key: ODATA-557 > URL: https://issues.oasis-open.org/browse/ODATA-557 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Improvement > Components: OData ABNF Construction Rules, OData ATOM Format, OData CSDL, OData JSON Format, OData Protocol, OData URL Conventions > Affects Versions: V4.0_CSD03 > Environment: [Proposed] > Reporter: Ralf Handl > Assignee: Ralf Handl > Labels: AdoptionBlocker > Fix For: V4.01_WD01 > > > IEEE754 also defines the DECFLOAT data type for high-precision decimal arithmetic. They have 16 or 34 decimal digit mantissas and exponents between -383 and +384 or -6143 and +6144. > Representing them exactly in current Edm.Decimal would result in at most 34 non-zero digits and several thousand zeroes. This waste can easily be avoided by allowing exponential notation also for Edm.Decimal. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
